How do you draw a line using C graphics?

Answer 1

its very easy just include the graphics directory in your program...

out put a dot on the screen.... in loop like..

Horizontal line from point A(x1,y1) B(x2,y2) start to out put the point from x1,y1 and then evry next loop keep y1 the same and increment x1 by 1.

Thanks

There is one more function in graphic library of C++, that is line().

It has four arguments of int type.

line(starting x coordinate, starting y coordinate, end x coordinate, end y coordinate);

setlinestyle() and setlinecolor() can be used for different line colors and line styles.

Answer 2

Use a continuous set of underscores? Something like this: ____________. Try that in your printf. If you use dashes, you will probably see spaces in between, but not with underscores. ( -------------- Vs. ________________ )

Answer 3

Hi, To draw a line in C, follow steps given below- 1. Load graphics Driver using the syntax: int gd,gm; initgraph(&gd,&gm,""); In this initgraph is a function defined in graphics.h header file. In this function gd is for graphics driver and gm is for graphics mode.Third argument is path to your .bgi file. You are preferred to keep your all .bgi and .chr files in bin folder so no need to give path for these things. .BGI files are graphics adapter so for good graphics you should use enhanced adapter you can take more details about these from help of turbo C++ IDE. Well, you can use EGAVGA.bgi. 2.Now You can use any graphics function like line, circle, rectangle etc. For drawing a line you can use following syntax: line(100,100,300,100); These are initial point and final points of a line respectively. 3.Finally you should close the graphics environment by using closegraph(); ,so control will return back to the text mode. It is not mandatory , but it is a good practice. Thanx n Regards Ajay vijaywargiya(SE) BMC s/w pune(India)

Answer 4

There are no built-in functions that can draw lines since C++ is a generic language and graphics are platform-dependent. Even the standard library does not provide any line drawing methods aside from printing ASCII line-drawing characters on the console. Even so, consoles are also platform-dependent; there are no generic methods of printing a specific character at a specific position.

To draw lines -- that is to say a straight line between two points within a viewport -- you will need a graphics library that supports your platform. OpenGL is your best option as it provides a generic interface.

Answer 5

Since all graphics are platform-specific, there are no built-in, generic graphics routines, including line drawing. To draw any graphics you will need a suitable API for your platform and hardware, thus the actual code will vary according to which system you are targeting.
